One thing that is not in doubt is that many UPFs are hyper-palatable. It’s much harder to overeat if the food in question is potatoes, carrots, and fish than if the meal is Pringles, Ice cream, and deep fried fish sticks.
There is a connection between ultra processing and hyper-palatability, but it is a very lossy one. Doritos are ultra processed but no honest definition of ultra processed foods can include Fritos. Are Doritos substantially worse for you than Fritos?
Is ice cream ultra processed? There are definitely ultra processed ice creams you can buy, with lots of stabilizers or whatever. But you can also make ice cream with just cream, milk, sugar, and vanilla beans. If anything, the homemade stuff that isn't ultra processed is even more hyper-palatable than the "frozen dairy dessert" kind.
The ingredients in Fritos are corn, oil, and salt. What processed additives? Is extruding cornmeal mixed with water through a die ultra processing?
This is spinning wildly into seed oil crank stuff.
Do you know how canola oil is made?
